Two magnetic storage cores have an output winding L 31 , L 32  which is common to both input and read-out signal pulses, and a writing winding L 21 , L 22  which is energized at the same time as an input pulse is applied to terminals Ti, Tia, the cores being switched from initially opposite remanent states to like positive or negative remanent states according to the input pulse polarity. Each application of coincident input and writing pulses is followed by a read-out pulse applied to terminals Tr, Tra, and currents I 1 , I 2  are passed through the respective output winding coils L 31 , L 32  which restore the cores to their initial opposite remanent states. Since only one core is switched by the currents I 1 , I 2 , an output characteristic of the input pulse polarity is developed across one half of a centretapped transformer Tra<SP>1</SP>. Rectifiers D 1  and D 2  isolate the input pulses from the transformer.

Abstract: 801,444. Transistors. STANDARD TELEPHONES & CABLES, Ltd. Sept. 5, 1956, No. 31527/57. Divided out of 801,442. Class 37. A method of fixing a lead to an electrode of a transistor comprises the steps of applying the lead to the electrode, passing a current between the lead and electrode so as to fuse the latter, pushing the lead into the molten electrode, cooling the electrode, applying a flux to the junction between the lead and the electrode, and then passing a further current to fuse the electrode to the lead. In one embodiment leads are fixed in this way to electrodes in the form of indium pellets 2, 3 which have been fused to opposite faces of an N-type germanium body 1 to form a PNP junction body by the method described in Specification 801,443. In an alternative embodiment the electrodes are lead or lead antimony pellets fused to a P-type body by the same method. It is possible to fix both leads in a single operation by using alternatingi currents passed between them via the semiconductor body. A base contact in the form of an open circle of gold-plated molybdenum, which is flash-plated with antimony if the body is N- type, is fused to the body about the indium pellet 2 by passing a current through it as described in Specification 801,442 from which the subjectmatter of the present Specification has been divided.

Title: Improvements in and relating to current generating and controlling appliances particularly applicable for use in electric arc welding
IPC: H02K23/10
Filed: 1925-12-18
Abstract: 267,612. Quasi-Arc Co., Ltd., and Strohmenger, A. P. Dec. 18, 1925. Supplying and controlling consuming devices. -An electric generator for arc welding has a shunt field winding and a series field winding tending to oppose strong fluctuations of current and the magnetic circuit is formed so that there are at least two zones located at different axial positions along the armature, one of which is saturated even at low armature voltages while another remains unsaturated practically throughout the whole working range. Fig. 1 shows diagrammatically a generator 1 having a shunt field winding 2 and rheostat 15, a back-compounding winding 3, and an interpole winding 6. The armature, Fig. 3, is stepped axially so as to provide a central unsaturated zone having a long airgap 18 and two saturated zones at the ends having short air gaps 21. This is effected by disposing the winding in slots which are open in the middle part while the teeth 19 project at the ends. Alternatively, the pole faces may be stepped. The series field windings 3 which are disposed near the ends of the poles so as to localize flux changes in the air-gap zone, are given a high self-induction by embedding them in slots, or the conductors themselves may be in iron. The shunt field winding is made with heavier wire and fewer turns than usual so as to reduce the time of building up the field, and the field poles are normally fairly saturated. To compensate for fluctuations, in the load circuit, a reactance is provided comprising cores 7, 10 carrying a primary winding 9 in series with the load and a secondary winding 11 in the shunt field circuit. These windings set up opposed fluxes. The limb 10 is preferably of cast iron so as normally to be highly saturated. The primary winding 9 is given a high self inductance by embedding it in the laminated core 7 or by constructing it of iron wire. With this arrangement, the reactance of the winding 9 is high when the load current is small, but with a heavier current, the effects of windings 9 and 11 more nearly counterbalance and the reactance is reduced. Tappings may be taken from the winding 9 and connected to a series parallel switch, and one or more air-gaps 8 which may be variable are formed in the core 7,

Abstract: 1,262,196. Infra-red thermograph. BARNES ENG. CO. 25 June, 1969 [3 July, 1968], No. 32061/69. Heading H4F. In a thermograph in which an X-Y scanning mirror 10 reflects incoming radiation from points in the field of view to be focused by a Cassegrain optical system 11, 12, on to an infra-red detector 14, a light chopper 25 providing a black body reference level signal, a light beam from a constant brightness tungsten filament lamp 26 is reflected by a mirror 22 secured to the mirror 10 to scan a light sensitive surface, e.g. a film, in synchronism with the scanning of the field of view, and the signals from detector 14 control a transducer 32, such as a pen recorder motor, which moves a variable filter 30 across the light beam to modulate the light reaching the fibre. In a second embodiment, Fig. 8, light from a source 66 passes through a condensing lens 68, is reflected by a fixed mirror 72 and a galvanometer mirror 76, and, after passage through a small aperture 82 defining the scanning spot, is reflected from a mirror (85) secured to the main scanning mirror and thus caused to scan the film. A stationary variable filter 70 is placed at the lens 68, or between its elements, so that the light passing through aperture 82 is modulated thereby according to the position of the mirror 76, which is controlled by the output of detector 14. Use of a beam splitter between the aperture 82 and the film minimizes coma, Fig. 7 (not shown). The filters may be continuously graded white-black or red-violet or comprise distinct bands for digital presentation. An opaque portion is provided for use during the flyback time. The bands may be separated by colourless transparent strips, or by opaque strips or both, to give isothermal lines, and a colourless transparent band may be included adjacent the coldest (violet or black) band to give an apparently hot background and show up otherwiseindistinguishable detail. A black-white banded filter may be provided with greater intensity charges at its white end compared to the black end to facilitate interpretation of the thermogram.
